This How To describes a method of patching SYSTEM/LOADER and installing it on an LX100.

The LOADER patch below enhances SYSTEM/LOADER to allow a file to be loaded from a Hybrid Library/Maintenance-Joliet CD.

This allows a COLDSTART from a Hybrid Library/Maintenance-Joliet CD. The patch was submitted with UCF #91466325 on 14th August 2002.

This patch is against MCP 5.0 SYMBOL/LOADER.

Use the SYSTEM/EDITOR to apply the LOADER patch to SYMBOL/LOADER and compile it as SYSTEM/LOADER.

Transfer the SYSTEM/LOADER file as a Binary Image to the Windows partition using FTP.

COPY [FTP] SYSTEM/LOADER AS 'SYSLOADR.EMD'(FTPTYPE=IMAGE)
  TO DISK(HOSTNAME=CPNTA,USERCODE='anonymous')

Replace the SYSLOADR.EMD file which is in the LX100 installation directory (C:Program Files\Unisys\Virtual Machine for ClearPath MCP\SYSLOADR.EMD).

Start the Console for MCP and use the menu MCP | Run System Loader to check that it runs.
